Natural Climate Change in Djibouti, Africa

As permanent as geographic features such as deserts may seem, Earth's climate and landscape are dynamic and constantly changing. Geologic evidence has revealed that parts of the Sahara were once lush and filled with animal species more often associated with the savanna far to the south. This video segment adapted from NOVA explains how Earth's position relative to the Sun might be responsible for the dramatic shift in the climate of what is now the Saharan nation of Djibouti.
